Trauma disease represents the fourth cause of mortality in frequency and the first one in terms of lifetime waste. It constitutes a significant health problem that provokes a high morbidity and incapacity in addition to striking health and social costs. Since now, its management approach has been done through patient data bases analysis and surveys directed to professionals. This research report attempts to elucidate epidemiologic, management and clinical results' comparability between actual adult BTI clinical practice in Catalan ICU's, which are of reference for this pathology, and practice shown in medical literature in our environment. The study was planned with a double main objective; for one part, to describe demographic and clinical patient characteristics, and for the second part, to analyse patient monitoring and therapeutic management. As secondary objectives we proposed to explore variability by BTI clinical severity, adherence rate to recommendations addressed in Clinical Practice Guidelines in force, and patient neurological outcome, identifying those epidemiologic parameters probably influencing neurological outcome, apart from secondary insults incidence. An observational and prospective study was conducted in 7 reference ICU's in Catalonia. Patient data collected covered demographic, clinical, radiological, monitoring and therapeutic aspects, besides complications and outcome variables for patients that were admitted in the ICU with a BTI diagnosis, with or without multiple trauma, that were followed in their length of stay for a 15-day period. A total of 370 patients were included in the study period of 1 year.Main results show a predominance of males with a mean age of 40, being traffic accident the main cause of BTI. 36% were directly admitted to the reference hospital, but only 26% were admitted in the first hour after the accident. The BTI severity profile was: 53% severe, 27% moderate and 20% mild, being the highest prevalence (39%) type II Marshall encephalic injury. The existence of SH was 49%. ICP was monitored in 69% of severe patients and SjO2 in 27% and TCD in 50%. Monitoring and therapeutic use was shown to increase depending on the higher patient severity. Close adherence to clinical guidelines recommendations was proven for systemic and neurological monitoring and barbiturate use, and was lesser the adherence for hyperventilation and corticoid utilization. ICU mortality rate was 22%, raising 31% for severe patients. Dependent variables for mortality were found to be pupil status, type of radiological finding, sex and BTI severity. Pre-hospital complications (hypoxia, hypotension, bronchial aspiration, cardiac arrest, hypothermia, convulsions) were found in 15% of patients, and are cumulative associated with a worse outcome.As a general conclusion, this research report supports the initial hypothesis that BTI clinical practice reviewed in reference Catalan ICU's, is comparable to practice in other countries of our environment, as is shown from the medical literature published.
